Abstract
The effects of the pallet unit-controlled atmosphere (PUCA) packaging system on the physicochemical quality and physiological changes in the kimchi cabbage (Brassica rapa L. ssp. pekinensis) harvested in summer, during cold storage at 2℃ were examined. PUCA packaging delayed the weight loss and trimming loss of kimchi cabbages during storage, irrespective of the O2 and CO2 concentrations. In addition, the cabbages stored using the PUCA packaging at 0.5% O2 + 2% CO2, 2% O2 + 2% CO2, and 2% O2 + 10% CO2 exhibited lower internal disorder/decay incidence rate than the control, and maintained the moisture content. The total phenolic content of the cabbages with PUCA packaging exposed to 2% O2 + 2% CO2 was higher after 80 days of storage compared to cabbages stored in the control conditions and in the PUCA packaging at 0.5% O2 + 2% CO2 or 2% O2 + 10% CO2. No significant (p>0.05) differences were observed in the pH, firmness, reducing sugar content, soluble solids content, and total glucosinolate content of the control and PUCA packaging samples during storage for 80 days. Therefore, these results indicate that the PUCA packaging system, at appropriate gas concentrations, can be useful in maintaining the quality of kimchi cabbage during long-term storage.
